If you haven’t taken a Ford Mustang with seriously respectable power to the track, then you are definitely missing out. What’s more, if you have, you know what a feat it is to get just that “perfect launch”…because it means everything in the ET. For the 2013 Shelby GT500, however, life just got a little easier at the track.
Ford has equipped the 2013 GT500 with a brand new launch control make sure every launch is fluid & efficient, every single time. A recombinant recipe of traction control and engine tuning ensure that the suspension, tires, and weight-shift are balanced when the powertrain is producing substantial power, in order to achieve “maximum thrust” (as SVT engineers put it).
While launch control might not seem like anything all that novel or special in the autosports realm, as-is applied to the 2013 GT500, the more promising thought to hold is that we could see this feature as an option, or perhaps even standard when the 2015 Mustang makes its presence known on the 50th Anniversary of the Ford Mustang. Now that is something to get excited about. For now, check out more details in the official Press Release from Ford Motor Company.
2013 Shelby GT500 Launch Control Spins the Wheels for Maximum Acceleration
DEARBORN, Mich., May 15, 2012 – Paraphrasing a classic quote – “With great power comes the need for great control” – the engineers at Ford’s Special Vehicles Team have stepped up to the plate to manage the massive output of the 2013 Shelby GT500.
Whether a driver is a track-day veteran or getting his first ultra-high-performance sports car, the new launch control system on the 2013 Ford Shelby GT500 will help ensure he gets smooth, consistent and fast starts every time.
Uncontrolled wheel spin is generally undesirable, whether commuting to work or racing away from the Christmas tree on a Friday night at the drag strip. Both safety and performance suffer when the wheels can’t get enough grip on the road. However, properly regulated, some wheel slip can be your friend.
“Launch control is essentially a special mode of the traction control system that integrates the brake and engine management systems to keep the tires balanced on the peak of the mu-slip curve in order to achieve maximum thrust,” explains John Pfeiffer, senior engineer, SVT Vehicle Engineering. “With so much more power and torque on tap from the new 5.8-liter V8, launch control makes it easier for drivers to take advantage of the performance.”
With launch control enabled, the driver just has to press the accelerator pedal to the floor and then smoothly and quickly release the clutch pedal just as he normally would when executing a clean start. The difference is that the electronics will automatically hold the engine steady at the desired speed and manage the rear brakes to allow the optimum amount of wheel slip for maximum traction.
“We recognize not every driver has the same style, and surface, tire and climate conditions vary,” said Eddie Khan, SVT Engineering supervisor. “Most of our competitors’ launch control systems have a fixed engine launch speed. We’ve given Shelby GT500 drivers the ability to adjust the engine speed to achieve best and most consistent performance, no matter where and when they drive.”
Shelby GT500 drivers can enable launch control in two ways – either through Track Apps™ on the 4.2-inch LCD in the instrument cluster or simply by tapping a switch on the left side of the instrument panel. When using the Track Apps screen, drivers can also adjust the desired engine speed for the launch in 100 rpm increments from 3,000 to 4,500 rpm. When first getting accustomed to launch control or if the pavement is cooler, a lower speed may be more appropriate. Switching to racing tires or running in an autocross event on a warm Saturday morning may call for a launch speed closer to the upper end of the range.
Once the desired engine speed has been set, launch control can be toggled on or off by tapping the instrument panel switch – more convenient than the intricate multistep process required on many other vehicles. After the launch control has been enabled or disabled, it retains that mode even after the engine has been switched off and restarted, something drag racers frequently have to do as they slowly make their way through the lines to the next quarter-mile pass.
“We developed this system to enable 90 percent of drivers to be able to achieve very fast, smooth and consistent starts with the Shelby GT500 regardless of their skill level,” said Khan. “Experienced drag racers may be able to get away slightly quicker, but chances are they won’t be as consistent.”
Veteran drag racers will find the Shelby GT500 also gives them extra flexibility. Switching off the traction control while the launch control is on produces an rpm-only mode that engine calibration engineer Tom Siebyla has tuned to keep the engine speed rock-steady with the electronic throttle and ignition without scrubbing off any speed with the brakes. Autocrossers or track-day racers can also mix and match the normal, sport and off modes of the stability control with the launch control to achieve the degree of sliding or control that best suits the conditions or their personal driving style.
For those times when there isn’t enough grip to use launch control effectively, such as dust or moisture on the pavement, Ford electronic brake control development engineer Dan Dunn has built smarts into the launch control that enable it to automatically switch off and revert to traction control.
“It’s not as intrusive as some TC systems have been in the past,” added Khan. “We wanted to help the driver make consistent starts without getting in the way.”
Launch control won’t do the driving, but it is a tool to help drivers extract consistent high performance from the most powerful production Mustang ever.
“For drivers who want to have some fun at their local drag strip with a stock machine, the 2013 Shelby GT500 is the ultimate bracket racer,” said Khan. “We’ve given our drivers the ability to exert control over all the power and torque this Mustang can produce.”
